Underground natural gas pipelines present a different set of hurdles for technicians. Even on bridge utility projects, certain lengths of a pipeline eventually go underground at the base of the bridge. For underground appliions, HDPE is the industry standard.
Underground gas piping shall be installed with approved clearance from other underground structures to avoid contact therewith, to allow maintenance, and to protect against damage from proximity to other structures, In addition, underground plastic piping shall be installed with approved clearance or shall be insulated from sources of heat so as to prevent the heat from impairing the Puhui Pipe manufacturer in China

4/11/2004· Pluing and Piping - underground natural gas line - Hello. I need to replace an underground gas line that runs from the meter in the back of my house to my shop, about 75 feet away. The previous Hello: Midwestlaker Water plastic line is not the correct material for Puhui Pipe manufacturer in China
HDPE is the material used in natural gas transmission systems pipes – these pipes are large in diameter and cover more than a quarter-million miles of our nation. Transmission system pipe is made of 1/4-inch to 1/2-inch thick HDPE, and has special coatings and "hodic" protection -- an electric current that controls corrosion on the metal surface through electro-chemistry.
24/7/2012· Natural gas can also be cooled to about -162 C (-260 F) and converted into liquified natural gas, or LNG. In liquid form, natural gas takes up only 1/600 of the volume of its gaseous state. It can easily be stored and transported places that do not have pipelines.

Just as the properties of different pipe materials vary widely (see Table 1), the importance of these properties varies widely between projects. The piping material chosen depends on the appliion and the water quality. For example, heating systems often employ Puhui Pipe manufacturer in China
15/6/2016· Biogas and natural gas are both produced by the breakdown of organic material by bacteria that metabolize the organics into primarily methane and carbon dioxide. Biogas and natural gas can include impurities such as hydrogen sulfide, mercaptans, and others (alkanes, nitrogen, oxygen and trace amounts of other gases such as helium).
13/4/2013· Normally YES, if the black pipe is Mill wrapped and or use hot applied coal tar enamel with 15# felt covering and tested for leaks with a "jeeper" 15,000 -20,000 AMPS to make sure there are no voids There are approved plastic covering materials but ask the local
These straight full couplings are designed for use with PGA gas pipe and tubing, as well as all gas, pluing, and propane appliions. They can help to create a permanent leakproof joint. Use these straight male adapters underground, natural, and LP gas tubing Puhui Pipe manufacturer in China
1/12/2013· I''m converting a portable generator to run on natural gas. I need to tap into my gas line in my home, run the line through the basement wall and then underground for about 25 feet. From there, the line will need to go vertical and rise above the ground level to around 16 to 24 inches where I plan on installing a secondary valve and an elbow with a simple pipe plug.
Where Equations 4-1 and 4-2 are used to size piping or tubing, the pipe or tubing shall have smooth inside walls and the pipe length shall be determined in accordance with Section 402.4.1, 402.4.2 or 402.4.3. 1. Low-pressure gas equation [Less than 1 1 / 2 2.
The material of choice for most above ground installations of natural gas piping is ASTM A53/A53M, black HDPE, Schedule 40, Type E or S, Grade B. carbon HDPE pipe. HDPE piping is used for systems operating in excess of 1,000 psig (6,900 kPa) and delivering natural gas to loions in excess of 300 miles from the last compressor station.
natural gas pipe. Made of high-quality PVC and synthetic materials, it is soft and elastic, safe and reliable, with good pressure resistance, good weather resistance and excellent sealing. High-quality raw materials produce no odor, strong bending ability and strong durability.
MDPE, being more flexible, is the material of choice for the underground gas piping appliions, and it is the type we sell at PexUniverse. HDPE pipe is less common is the gas industry and usually is intended for non-residential appliions with high pressures (up to 125 psi).
